{We present results from Chandra HETGS (250 ks over two epochs) and XMM-Newton EPIC and RGS (60 ks) observations of NGC 2110, which has been historically classified as a narrow emission line galaxy. Our results support the interpretation that the source is a Seyfert 2 viewed through a patchy absorber. The nuclear X-ray spectrum of the source is best described by a power law of photon index {$\Gamma$}\~{}1.7, modified by absorption from multiple layers of neutral material at a large distance from the central supermassive black hole. We report the strong detections of Fe K{$\alpha$} and Si K{$\alpha$} lines, which are marginally resolved with the Chandra HETGS, and we constrain the emission radius of the fluorescing material to {\gt}\~{}1 pc. There is some evidence for modest additional broadening at the base of the narrow Fe K{$\alpha$} core with a velocity \~{}4500 km s$^{-1}$. We find tentative evidence for ionized emission (O VIII Ly{$\alpha$}, an O VIII RRC feature, and possibly a Ne IX forbidden line) in the Chandra MEG and XMM-Newton RGS spectra, which could be associated with the known extended X-ray emission that lies \~{}160 pc from the nucleus. We suggest that the 10$^{23}$ cm$^{-2}$ partially covering absorber originates in broad-line region clouds in the vicinity of the AGN, and that the 3{\times}10$^{22}$ cm$^{-2}$ coverer is likely to have a more distant origin and have a flattened geometry in order to allow the small-scale radio jet to escape. }
